  Technical description

  This material is a two-component Kneading silicone rubber, specially developed for precise mold impressions, model making, prototypes and technical applications.
  The simple Mixing ratio 1 : 1 makes it easy to process the product manually or mechanically. After curing, an elastic, dimensionally stable silicone with an average hardness of about Shore A 50 is formed.
  The hydrophilic surface ensures very good wetting and enables an exact reproduction of even the finest structures.

  Technical data

  • Type: Two-component kneading silicone (A +B)

  • Mixing ratio: 1 : 1 by weight or volume

  • Hardness: approx. Shore A 50

  • Viscosity (before curing): pasty, easily malleable

  • Surface: hydrophilic, detailed

  • Storage stability: at room temperature and closed packaging for several months

  • Color: neutral/ bright (depending on batch)

  Advantages

  • Very accurate reproduction of details thanks to hydrophilic surface properties

  • Easy handling – no complicated dosing or additional catalyst necessary

  • Elastic and dimensionally stable – withstands multiple impression processes

  • Versatile – ideal for mold making, model making, casting, design and engineering models

  • Good temperature resistance (up to about 200 °C with short-term load)

  Processing instructions

  1. Preparation: Clean and dry the surface of the original. Remove dust, oil and grease.

  2. Measure: Weigh components A and B exactly in a ratio of 1: 1.

  3. Mix: Mix both components thoroughly until a uniform color and consistency is achieved (about 2-3 minutes).

  4. Optional – Venting: For very fine structures, the material can be vented in a vacuum.

  5. Apply / Shape: Apply the silicone evenly or put it in the mold. Avoid air bubbles.

  6. Curing: Let it cure completely at room temperature (depending on temperature and layer thickness).

  7. Demolding:Carefully remove from the mold after curing. If necessary, use release agent.

  FAQ – Frequently Asked Questions

  Q: Does an additional catalyst need to be used?
  A: No, the material is self–hardening – just mix components A + B in a 1 : 1 ratio.

  Q: Can the cured silicone be cut or sanded?
  A: Yes, after curing, the material can be machined mechanically.

  Q: Is the product suitable as a molding material for resins?
  A: Yes, with the appropriate release agent, it can be used for epoxy or PU casting resins.
